Polarized twisted conics and moduli of stable curves of genus two

Algebraic Geometry 2021-03-25 v1

Abstract

In this paper we introduce the stack of polarized twisted conics and we use it to give a new point of view on M2\overline{\mathcal{M}}_2. In particular, we present a new and independent approach to the computation of the integral Chow ring of M2\overline{\mathcal{M}}_2, previously determined by Eric Larson.
